Abstract
本試驗以單雜交玉米臺農351號及臺農育365號爲材料，兩者具相同母本及不同父本，且後者子粒充實性優於前者；於1986年秋作進行田間試驗，在吐絲後連續針對穗位葉鞘、節間與果穗上位（自穗基算起之80-90%長度）及下位(20-30%)穗軸取樣，分析醣類組成，目的在確定植株供源能力與子粒充實需求間之平衡關係，供爲進一步探討影響碳水化合物自玉米穗軸傳移至子粒因素研究之基礎。試驗結果發現臺農351號穗位葉鞘及節間在吐絲後7週內之非構造性碳水化合物濃度均在20%以上，顯示供源充裕，子粒充實後期之蔗糖濃度雖明顯下降，但仍以子粒充實性較差之臺農351號的濃度較高，亦即不爲導致基因型間子粒充實差異的原因。Corn hybrids Tainung 351 (TNG 351) and Tainung Yu 365 (TNGY 365) were used as experimental material. The two hybrids have the same maternal inbred but different paternal inbred. The latter hybrid was superior to the former in kernel-filling characters. Field experiment was conducted in the fall crop season of 1986 to study pattern of changes in carbohydrate concentations of leaf sheath and internode at the ear-node and apical and basal portions of the cob. The purpose was to study the relationship between source ability and sink demand of the two hybrids.
